WA Salt Supply was founded in 1945 by three brothers: Arthur, Jack, and George Lister.
Before this time the brothers had been involved in goldmining in the goldfields at Widgiemooltha, Western Australia.
Falling gold prices and a shortage of salt available on the local market led the Lister brothers to consider a change in career.
The Listers turned their hands to harvesting salt from Lake Lefroy, a natural salt lake near Widgemooltha. In the beginning the salt was shovelled by hand into carts pulled by horses, and packed in hessian bags.
Later trucks were introduced, some of which sank below the surface of the lake under their heavy loads.
In 1953 the youngest brother, Arthur, moved to the Port of Fremantle to establish a packaging and distribution centre for the salt harvested from Lake Lefroy.
Over the years the demand for salt in Western Australia greatly increased, largely due to the emergence of chlor-alkali industries requiring substantial tonnages of salt.
Over time, newly emerging markets developed for salt in domestic swimming pools, oil exploration, food processing, and water treatment. In the early 1970s, as the demand for salt increased further, the family relocated their activities to Lake Deborah, Koolyanobbing.
At Lake Deborah salt was available in larger reserves, at higher quality, and in closer proximity to rail infrastructure. At the same time the Lister family established a new salt operation on the Pink Lake, at Esperance on Western Australia's southern coast.
The salt from this lake would cater for the skin and hide treatment plants in the state's south-west.
